Title: Focus spot evaluator
Inventor: NAKAMURA HARUJI
IPC: G01J1/02
Filed: 1988-12-07
Abstract: PURPOSE:To obtain a quantity of light distribution chart with a clear focus free from distortion by calculating a shape of a focus spot from a relationship between position information in the revolution of a glass disc and a change in the quantity of light during the passage of a slit. CONSTITUTION:There is a window section 19 with a deposited film for reflection removed in a slit on the surface of a glass disc 12 and the window section turns in the direction of the arrow 20 with the rotation of the disc 12. The quantity of a laser light transmitted therethrough 19 increases with the movement of a front end 19a of the window section 19. A change in the quantity of light is received with a photosensor 15 and outputted as electrical signal. A focus lens 1 is subjected to a focusing control to focus on a reflecting surface thereof. A motor 13 spins the glass disc 12 while a motor 14 revolves the glass disc centered on optical axis of a focus lens 1. A computing section inputs information on revolving position and a change in quantity of light to calculate a quantity of light distribution of a focus spot.

Title: Cache memory control system
Inventor: FURUTA HIROKO
IPC: G06F12/08
Filed: 1989-11-29
Abstract: PURPOSE:To improve the cache hit rate by dividing a tag memory into two parts having different cache systems. CONSTITUTION:The 1st and 2nd tag memories 1 and 2 serving as the data memories select the different cache constitutions out of a direct mapping system and several types of way set associative systems. For instance, the memory 1 adopts a 2-way associative system and the memory 2 adopts a 4-way set associative system respectively in terms of the cache constitution. When an input address is supplied, some address part reads an address out of plural data memories having the cache constitutions of different systems. Then a hit deciding circuit 5 decides a hit or miss state of the read address. As a result, the cache hit rate is improved.

Title: Semiconductor memory
Inventor: KOBAYASHI TOMOKO
IPC: G11C11/41
Filed: 1990-11-15
Abstract: PURPOSE:To reduce a product finishing man-hour of a semiconductor memory and prevent complexity in production process management by judging any signal which is applied to an any input pin of the semiconductor memory and then switching a plurality of word configurations. CONSTITUTION:When a signal with a normal cycle width or more is applied to any input pin P1 or P2 or both of these before power is turned on, a high or low-level signal is generated at outputs phi1 and phi2 of a signal judgment circuit which judges the width and then three patterns, namely high-high, high-low, and low-high, are outputted to outputs phi3 and phi4 of a word configuration determination circuit. They are input to the word configuration latch circuit, thus enabling the phi3 and phi4 to be latched. Once they are latched, these levels are retained by the latch circuit although noise may appear at the input pins P1 and phi1 after the power is turned on and the word configuration does not change until power is turned off.

S at a high ratio to form the Al-Si killed steel and adding a desulfurizing agent to this steel to desulfurize the molten steel, then blowing gaseous O2 while adding Al thereto thereby oxidizing away the Al of the Al-Si killed steel. CONSTITUTION:Alloy irons, such as Al, Fe-Si and Fe-Mn, are added into the molten Si killed steel in a ladle 2 to convert the molten steel 1 to the Al-Si killed steel contg. >0.012% Al. An immersion pipe 4 is disposed above the surface of this molten steel and a bubbling lance 6 is immersed into the molten Al-Si killed steel below this pipe. An inert gas, such as Ar, is ejected from this pipe to remove the molten slag 7 on the surface of the molten steel below the immersion pipe 4 and thereafter, the front end of the immersion pipe 4 is immersed into the molten steel. The desulfurizing agent, such as quicklime, is then blown from the lance 6 to desulfurize the molten Al-Si killed steel. While the Al is added from a charging pipe 5 of the immersion pipe 4 in succession thereto, the gaseous O2 is blown by the lance 3, by which the Al in the Al-Si killed steel is oxidized away and the Si killed steel of the low S content is produced.

IPC: H04N1/393
Filed: 1988-12-08
Abstract: PURPOSE:To attain the reduction of a binary picture compensating the disadvantage of the projection method such as missing of a thin line by detecting it that a pattern of a reference picture element is a pattern requiring the predetermined correction with respect to an output value (projection) of the projection method around a noted picture element, and applying a positive or a negative correction value. CONSTITUTION:For example, 3X3 block data D1.1-D3.3 from a line buffer 1 as shown in figure (b) are inputted to a projection value calculator 2 and a correction value calculator 3. The projection value calculator 2 calculates a projection value sum by using matrix values a1.1-a3.3 as shown in figure (c) in a memory 5 according to equation I. The correction value calculator 3 uses the block data D1.1-D3.3 from the buffer 1 and the reduced picture element obtained already as reference picture element data and outputs a correction value mod. Then a correction projection value sum + mod is obtained by an adder 7, a comparator 4 binarizes the value of a threshold level memory 6 to output 1 or 0. Thus, in the case of a predetermined specific pattern, a positive or negative correction is applied to the projection value to prevent missing of a thin line.
